To all whom t may concern Be it known that l, ALBERT E. WILLrAMs, acitizen of the United States, residing in Jersey City, Hudson county,and State of New Jersey, have invented certain new and usefulllmprovements in Circuit-Closers, of

which the following is a specification.

rlhe object of my invention is to provide an electrical device which ispositive in its action, whereby a .prescribed vwater level may hemaintained within a tank or other receptacle, and in case such waterlevel falls below a prescribed point, an alarm or other electricaldevice will be operated either to attract the attention of the properAparty in charge of the tank, or an electrical pump or other mechanismreleased to re-llthe tank to its proper level.

The invention consists in inclosing two electrodes of conical shape, onewithin the4 other within a chamber or compartment, each of saidelectrodes being composed of a metal of high conductivity, means' forelectrically connecting said electrodes with a source of electricity,means for adjusting,

is partially broken away, an electrical cir-- cuit, motor, pump andother devices being shown diagrammatically; Fig. 2, is a cross 'sectionon plane of line 2-2, Fig. l.

lt is to be understood that l do not limit myself to the identicalform-and structure of'device herein shown, as many mechanical expedientemay be resorted to without departing from the spirit and intent of myinvention.

ln the drawings A, represents a portion of a tank or other receptaclefor containing a liquid, to which my signaling device l,l

may be attached.

rlhe device B, consists of a cylindrical or other shaped casing b, ofnon-conducting material, provided with the upper and lower Ament h3.

flanged plates b,`2, forming a compartment bg, inclosing the electrodesE, E".

To the upper hanged plate is adjustably connected the invertedcone-shaped electrode E, composed of metal of high conductivity. 'llothe lower hanged plate b2, (but insulated therefrom as at b4) ispermanently connected a second electrode E', of conical shape alsoformed of metal of high conductivity.

Both of the electrodes E, E', as shown in the accompanying drawings havethe perforations e, e", the purpose of which will be more fullyexplained.

The electrode E, is made adjustable with relation to the electrode E',by means of the adjustable threaded rod r, connected to the 'cross bare3, on the upper end of the electrode E, and the adjusting nuts r', r2.

The electrode E', is permanently held in the lower or bottom flangedplate b2, but insulated therefrom by insulation b4. This electrode isconical-shaped, and at its lower extremity is formed with an opening p,into which a pipe p', enters and connects the dev ice to the tank A,thus permitting of the liquid or' other duid to enter the compart-'llhis pipe p', is also insulated fromv the tank A., at p2.

Both 'electrodes E, E', are preferably though not necessarily perforatedas at e, e', j

for the purpose of permitting of a free and unobstructed circulation ofthe water or other liquid between them, thus insuring an electricalcircuit which may be regulated as to density by adjusting the electrodeE.

The upper electrode is adjustable so that the gap between the same andthe lower electrode can be increased or decreased to meet the variousdensity of the liquids or waters that contain various quantities ofsaline matter which increases the amperes or current flowing across thegap and overcomes the diderent resistance by the surface saturation ofthe electrodes. Ylhe formula of passing electricity through p-ure waterthe tank when the water falls below the water line W-W, I have showndiagram- 'matically in Athe drawings, a solenoid L,

interposed in the y electric circuit w, lw. Upon the tank being filledwith water to the proper level W-W, and the water in the comlpartme'ntb3, having attained the same level,

the electric circuit between the electrodes E,

E', is closed and through themagnetic inment b3, again falls below thewater -level 'W-W, in which case the circuit between the electrodes EE', is again broken, the pivoted arml Z, re eased from the solenoid L,closing the circuit between the motor M, starting the pump P, therebyre-lling the tank A, until it again is lled to the proper water level,when the above operation is repeated.

y The `adjustment of' the electrode E, by

means of the adjusting rod r and' nuts r', r2,

with relation to the electrode E', is an mportant feature of myinvention, as it permits of regulating the current'between theelectrodes with relation t0 the potential, so that almost any desireddegree of electrical current may be obtained.

rlhe conical shape of the electrodes is another important feature inthat I am enabled to make an electrode of large surface of conductivity.

I have herein described my device in connection with maintaining a waterlevel, but it is obvious that other liquids or fluids may be used withlike result and it is to be understood that I do not limit its use towater.

What I claim as my invention and desire to secureby Letters Patent is,

l. In a device of the character designated, in combination with a tankor receptacle for containing a liquid, a casing connected with said tankinclosing two electrodes of conical shape, means for maintaining anelectric circuit between said electrodes, for the purpose described. l

2. In a device of the character designated, in combination with a tankor receptacle for containing a liquid, a casing connected with said tankand inclosing two electrodes of conical shape, means for adjusting oneelectrode with relation to the other, means for maintaining an electriccircuit between said electrodes for the purpose described.

3. lIn a device of the character designated, in combination with a tankor other receptacle for containing a liquid, a casing connected withsaid tank inclosing two electrodes of conical shape, each of saidelectrodes being perforated for theA purpose described, means formaintaining an electric circuit between said electrodes.

4. In a device of the character designated, in combination with a tankor other receptacle for containing a liquid, a casing connected withysaid tank inclosing two electrodes of conical shape, means foradjusting one electrode with relation to the other, each of saidelectrodes being perforated for the purpose described, means formaintaining an electric circuit between said electrodes, for the purposedescribed.
